3Claims. (class-s8) This invention relates generally to indexes, and particularly to an index memo pad.

The main object of this invention is to construct a simple and efficient form of index memo pad which can be opened in a manner that every line on both sides of every page thereof may be easily written upon and read. I

The second object is to construct a pad of the class described which will be completely visible throughout the entire length thereof.

The third object is to construct a pad of the class described in a manner that the fingertips will be guided into accurate register with the various subdivisions .of the index and also that although the pages are loosely hinged together, they are accurately superimposed when the pad is in a closed position.

The fourth object is to construct a pad of the class described having index tabs so disposed and identified that a desired section may be exposed to view by placing the fingertip under a given tab upon the upper side of which the identifying characters are shown and then lifting the portion of the index resting upon the tab.

The fifth object is to construct an index of the class described in which is provided a convenient cross index and in which it is possible to turn backward or forward from a given setting without first closing the index or performing any preliminary movements or operations.

The sixth object is to so construct the device that it will be simple to manufacture and assemble and in which the removal and replacement of an index with relation to its base is a simple operation to perform.

The seventh object is to construct a device of the class described in which the necessary operations are natural ones leaving the user of the index the better use of his time and attention to the recording or the reading of a given item.

The eighth object is to construct a device of the class described wherein the tips of the fingers are deflected away from the body of the index sheet just prior to their contact with the tab on the desired sheet.

These and other objects are accomplished in the manner set forth in the following specification as illustrated in the accompanying drawings, in which:

Fig. 1 is a plan of the preferred form of the device showing the index closed.

Fig. 2 is a plan of the device showing the index opened to the IJ section with a portion of the index pages broken away to disclose a calendar at the back of the index.

Fig. 3 is a side elevation of the device.

Fig. 4 is a fragmentary section taken along the line 4-4 in Fig. 3.

Fig. 5 is a fragmentary section taken along the line 5-5 in Fig. 2. v 5' Fig. 6 is a perspective view showing the underside of the device.

Fig. 7 is a section taken along the line 1-?! in Fig. 2.

Fig. 8 is a perspective view of a modified form of the device showing the index without the base.

Fig. 9 is a perspective view showing the same index from the back thereof.

Fig. 10 is a section taken along the line Iii-4|] in Fig. 2.

Fig. 11 is a section taken along the line ll-ll in Fig. 13.

Fig. 12 is a perspective view of a modified form of the base.

Fig. 13'is a perspective view showing the manner in which the index is operated.

Fig. 14 is a side elevation showing the index illustrated in Fig. 13.

Fig. 15 is a fragmentary section taken along the line l5--l5 in Fig. 13.

Similar numerals refer to similar parts throughout the several views.

Referring in detail to Figs. 1 to 10, inclusive, of the drawings, there is shown a slopingbase 15 having the downwardly extending sides l6 and ll, an upper end l8 and a lower end l9. The. upper and lower ends l8 and I9 have their edges 20 and 2| extending above the upper face 22 of the base I 5 and also have the inturned lips 23 and 24 which extend beyond the edge 25 of the base IS.

The side I! is provided with a plurality of indentations 26 which register with the index tabs 21 on the various sheets of memo paper 28. Each tab2'l has indicated thereon a plurality of letters or other characters 29.

It will be noted that the edges 30 of the various pages 28 are offset from the edge 25 of the base IS in order to prevent the accidental picking up of a page below the one desired.

It will also be noted in Fig. 4 that the upper end 3! of each indentation 26 flares outwardly to the edge 25 in order to cause the operating finger 32 to'be deflected away from the edge 30 of the lower sheets 28.

The various sheets or pages 28 are provided with perforations 33 through which extend the tongues 34 of the cylindrical binding 35. It will be noted that the rearmost cover 36 is provided with perforations 31 to receive the screws 38 which pass through the openings 39 in the base l5 into the clamping nuts 48 which extend slightly above the bottom edge 4| of the base 15.

It is desirable to employ a calendar 42 on one of the pages 28 of the index.

It is also desirable to cut an opening 43 in the back cover 36 to give access to the recess 44 formed in the base l5 for the reception of a memo pad 45.

With this form of the device it is a simple matter to replace the entire index by merely removing the nuts 40. When a type of hinge is employed, which is itself attached to the base 15, the screws 38 may, of course, be dispensed with.

In the form of the device shown in Figs. 11 to 15, inclusive, there is shown a flat base 41 having are threaded the screws 52 of the rubber feet 53 upon which the base 41 is supported.

It is desirable to provide the base 4'! with a plurality of slots 54 along one edge thereof, the underside 55 of which is preferably cut away as shown. The slots 54 are of a nature to receive the hinge element or binding 35. The index cover 56 and pages 28 are the same as in the first described form of the device.

In the form shown in Figs. 11 to 15 is illustrated the simplest form of the index in which however the operating principle of the first described form of the device is maintained.

It will be seen that in either of the forms of the device herein illustrated a variety of materials may be employed, such as wood, plastic, rubber, metal, etc. without departing from the spirit of this invention. Numerous other details may be modified in keeping with the particular style and grade of index being manufactured.

It will be noted from the foregoing that by this construction there is little if any possibility of injuring the tabs due to use owing to the manner in which they are protected and due to the fact that they are elongated far beyond the length of the ordinary index tab.

I claim:

1. An index having in combination a base having secured to the upper side thereof a hinged index provided with laterally projecting tabs and having serrations formed in the edge of said base registering with said tabs, each of said serrations having a deflector at the upper end thereof for guiding the fingers away from the body of the index.

2. The combination of a base having a plurality of pages loosely hinged to one edge thereof, said base having stops at the upper and lower endsthereof for holding said pages in horizontal alinement and stops along the open side of said index for holding said pages in vertical alinement, the various pages of said index having index tabs formed thereon which project beyond the outermost edges of their respective pages, the outermost edge of the base having serrations formed therein registering with the tabs in said index, the uppermost edge of said serrations extending to a line between the outermost edges .of the pages and the outermost edges of the tabs.

3. Ina device of the class described, the combination of a base, a plurality of superimposed pages loosely hinged along one edge thereof and attached to said base, index tabs projecting from the edges of said pages opposite the hinge and means for bringing said loosely hinged pages into accurate register when in a closed position, said base being characterized by having serrations formedin one of its edges registering with the respective tabs.
